Exchange Meeting Room Statistics

A while back I wrote an article named Exchange Meeting Room Statistics about a script to gather statistics regarding Exchange meeting room usage for MSExchange.org. For this script to work, we have to give ourselves FullAccess to the meeting rooms’ mailbox, add them into our Outlook profile, and then use an Outlook COM Object to connect to Outlook and gather this information. Far from ideal, especially when trying to analyse dozens of rooms!

I have finally written a new version that uses Exchange Web Services to gather the same information, plus some further stats. All the script requires is for AutoDiscover to be working, the EWS Managed API to be installed, and for the user running the script to have Reviewer permissions to the meeting rooms’ calendar (FullAccess permissions to the room’s mailbox will also work).

UPDATE (15/12/2017): I have updated the script to also work with Exchange Online (Office 365). If you want to analyse meeting rooms in EXO, simply add the -ExchangeOnline switch when running the script.

UPDATE (March/2020): I have finally written this newer version, specifically targeted at Exchange Online only, this time using Graph API! Please check it here.

This new EWS script, available in GitHub, will gather statistics such as the number of meetings during the specified times, the total and average meeting duration (in minutes), the total and average number of attendees, how many meetings started in the morning and afternoon, how many recurring meetings, and the 5 five organizers and attendees. It will export all the stats to a CSV file and also print in on the screen:
